The study is an investigation into the ”Effect of Nigerian films on Christian Youths in Pentecostal Churches in Kaduna state, Nigeria.” On the background that Nigerian films stimulate and propel youths to thick and act as they have seen. Nigerian films have become a silent tutor in many homes, it has turned into a subtle platform, where many young minds are defiled and besmirched, through extremely violent movies, horrific crimes scenes and uncensored display of sexual perversion which is against the norms, culture and tradition of Africans which advocates modesty and decency in dressing and character. The main objective of the study is to find out the effect of Nigerian films in the lives of Christian Youths in Pentecostal Churches in Kaduna State. In doing so, four objectives were formulated. To identify the moral effect of Nigerian films on Christian Youths in Pentecostal Churches in Kaduna State, identify the psychological effects of Nigerian films on Christian Youths in Pentecostal Churches in Kaduna State, identify the social effect of Nigerian films on Christian Youths in Pentecostal Churches in Kaduna State and identify the academic effect of Nigerian films on Christian Youths in Pentecostal Churches in Kaduna State. Four research questions and null hypotheses were set and tested at 0.05 levels of significance. A survey research method was adopted and the population for the study is 13400. A proportional sampling technique was used to obtain the number of respondents from the sample size of 364 from three senatorial zones of Kaduna State. A structural questionnaire was the instrument employed to collect data. The researcher with help of one research assistant administered the questionnaire. A total number of 364 copies of the questionnaire were distributed to the respondents and 358 copies representing 98.4% were duly filled and returned. The data collected through the questionnaire was presented and analyzed using tables. In the analysis of the data: location, gender, age and qualification were the demographic variables analyzed with frequencies and percentages. Also, the items raised in the study to answer the four research questions were tested with means, standard deviation, independent t-test and Analysis of Variance (ANOVA). The findings of the study were quite revealing. In the test of hypothesis one, the groups involved differed in their opinion on the moral effect of Nigerian films on Christian Youths in Pentecostal Churches in Kaduna State. Hypothesis two, three and four showed no significant difference in opinion on the psychological, social and educational effect of Nigerian films on Christian Youths in Pentecostal Churches in Kaduna State. The Conclusion drawn from the study indicates that Nigerian films have negative moral effect on the Christian youths and it also reduces interest in religious activities which exposes them to learn immoral behaviours. The recommendations from the study suggest that Nigerian films should be devoid if immoral acts but subtlety propagating the gospel through programmes that dwell on supremacy of Christ over Africa traditional gods and beliefs. There should be a censoring body that should include head of Christian bodies like Pentecostal Fellowship of Nigeria (PFN) to profile the film from professional Christian TV houses like Liberty film to encounter the available Nigerian films.
